My understanding is that all of the QR codes being scanned by Chinese users in WeChat are actually just encoding plain old URLs. I'm not a WeChat user, but this suggests to me that if I (painfully) handed out the big long WeChat URL for my restaurant or taxi or whatever, and the end user cared to enter it, the QR code would not be needed.
Is this true for most uses of QR codes ? They are just encoding URLs ?
I see that the Animal Crossing videogame allows users to pick up new designs by scanning QR codes - are those also encoded URLs ?
Or, is there broad adoption of QR codes for encoding other information not in URL format ?
